cjk – CJK language support

CJK is a macro package for LaTeX, providing simultaneous support for
various Asian scripts in many encodings (including Unicode):

Chinese (both traditional and simplified),

Japanese,

Korean and

Thai.

A special add-on feature is an interface to the Emacs editor
(cjk-enc.el) which gives simultaneous, easy-to-use support to a bunch
of other scripts in addition to the above — Cyrillic, Greek,
Latin-based scripts, Russian and Vietnamese are supported.
